WINDOW STOP Gaylord F. Krouse, Mason, Mich.

Application September 28, 1946, Serial No. 699,965

This invention relates to window stops and is particularly concernedwith a friction window stop.

It is common practice in the prior art to stop window sashes by means ofweights which are fastened to one end of a cord or band, theother end ofwhich is fastened to the side of the stile of the sash, the said cord orband passes over a pulley secured to the upper portion of the outsidelining of the sash, and the weight allowing the window sash to bestopped at any desired height. There is serious objection to the use ofsuch means for the purpose above-mentioned since considerable expense isinvolved and because moving parts are involved there is a predispositionto wear and breakage. In the event that the cord or band is broken thesash must be removed and the window frame must also be taken apart togain access for repairing the said cord, band, or other working parts.Also in the painting of the window frame the cord or band must be pulledaway from the said frame to accomplish the painting. Furthermore, thereare other objections and disadvantages to the use of the window stopsabove-described.

It is an object of my invention to provide a window stop without theneed of weights, cords or hands, and pulleys. It is a further object toprovide a window stop which is easily accessible. It is still a furtherobject of my invention to provide a window stop whereby the window canbe readily raised or lowered and can be stopped at any desired position.It is a further object to provide a window stop whereby the stopping ofthe window is accomplished by means of friction.

I have now discovered and invented a window stop which in combinationwith a Window sash and a window frame comprises a square block having ahole through the center thereof, and a pair of slots located oppositeeach other and being substantially equidistant from the said hole; asecond square block provided with an ex- 7 tending member, the saidextending member havslidably secured to the blocks of the window stop,

whereby I am able to accomplish the objects set forth and am able toavoid the disadvantages present in the window stops presently in use.

Referring to the drawing:

Fig. l is a portion of a window sash and a portion of a window frame,cut awa to show the invention in place.

Fig. 2 is a sectional view taken along line 2-2 of Fig. 1, showing theend of the sash, with the weather stripping and the window stop of myinvention in place.

Fig. 3 is a sectional view taken along the line 33 of Fig. 1, showingthe weather stripping and plan view of the window stop in place.

In Fig. 1 the window sash is slidably secured in the weather stripping2, which stripping is fastened to the frame 3 by means of nails 4. Thesaid weather stripping 2 is set in the groove 5 in the sash I. The block8 of the window stop of my invention is secured in the groove of thewindow sash by means of screws 6. Two flat springs 1 are fitted intoslots provided in blocks 8 and 9, and held in position by screw 19threaded into block 8. The screw It! can be turned to tighten or loosenthe springs 1. By tightening the said screw [0 the two springs arecurved toward each of the two sides of the inside of the weatherstripping. Thus the friction of the springs on the sides of the weatherstripping can be increased or decreased depending on the extent ofcurvature of the arc of each of the two springs. The window can thus bestopped at any desired height by the friction produced by the springsagainst the inside surface of the walls of the weather stripping.

While the window stop of my invention is very convenient in use forwindows of houses of ordinary construction I want to point out that thewindow stop is particularly adaptable to houses of pre-fabricatedconstruction. It is relatively easy to install and requires relativelylittle maintenance during use.

I claim:

A window stop comprising a square block having a hole through the centerthereof, and a pair of slots formed in the said block located oppositeeach otherand being substantiall equidistant from the said hole; asecond square block provided with an extending member, the saidextending member having a pair of holes, the said second block having athreaded hole through the center thereof; a pair of slots formed in thesaid second block located opposite each other and being substantiallyequidistant from the said hole, a pair of flat springs, the ends ofwhich are inserted into a slot of each of the said blocks;

and a threaded bolt passing through the hole in the said first block,and being threaded into the hole of the said second block, and means forsecuring the said window stop to a window sash substantially as shown.
